[AccessD] Automatic backup

[James Button]

Yup!

But the number of times I was complained to about a backup not working - 
As in the backup had been taken while the multi-user app was still open - 
Someone had just gone home without closing down their login, or their connection


And FileHistory (part of win 7 through win 10) - currently being proffered as
the backup facility to rely on 
 will take backup copies of files while the apps are using them!

 I wasn't being clear.

 "can't" in that you should not, not that you can't do it.  "Backup" in the
sense that your going to use a file copy.

 To get a valid backup by any means, you need all the users out, which means
you can't do a backup from within the app itself.

Technically that's Wrong 

- you can back it up while open - 
Just the App (DBMS) will probably decline to open the backup - that being on
the
basis that the copy shows it is already open - and in use.

You don't discover that until you actually need to open the backup with the
DBMS

 You can't backup a currently opened DB.

 There's no locks held on a DB so you can do the file copy.   But if another
user is in, or even in your own process if any background tasks are
processing, you might end up with an inconsistent DB.

 Of course you could do that in a small utility DB.

What is wrong with

Set FSO =CreateObject ("Scripting.FilesystemObject)
On Error Resume Next
Kill strPathtoBackupFile
On Error Goto 0
FSO.GetFile (currentDb.Name).Copy strPathtoBackupFile
